Turns out EA are releasing a spore/sims game very similar to the one Erhama described a few weeks ago.Not called Sprims, instead "Spore: Creature Keeper" It'll be targeted towards younger audiences, where you, the creator, looks after Spore creatures in a very similar fashion to that of The Sims.

The studio's also handling Spore: Creature Keeper, a standalone PC product targeted at a younger audience. Described as "like a mini-Sims" game, it will see players nurturing a newly born creature that has "Sims motives like energy and bladder".

Since it's targeted at a younger audience I have a feeling it won't be as epic-awesomeness as you think.I'm imagining a little dog/cat-like alien that you have to look after. Like Tamagotchi and those other virtual pets are - except with spore-like graphics and a Simmy UI.
